Analyzing VoLTE and VoWi-Fi

As IMS based VoLTE becomes the prevalent voice service enabler for 4G, this course provides detail on how the VoLTE and often associated VoWi-FI network operates. This is achieved through analysis of the network architecture and also key focus on SIP. Example call flows related to VoLTE and VoWi-Fi will be explored, including IMS, PCC and LTE interaction. The media stream will also be analyzed, with focus on the operation of RTP, the AMR and EVS codecs and also the use of SDP. Finally, interoperation with the PSTN and also mobility scenarios (SR-VCC and ICS) will be explored.This course will contain the following sections:
